A Step-By-Step Approach To Nutrient Removal
As stricter ammonia and nitrate regulations get rolled out, the City of Boulder rolls right along with them, improving plant processes in stages to ensure continued compliance.
Slated for June 9 to 13 at the Colorado Convention Center, ACE13 will again focus on the issues and technologies that are shaping the face of the drinking water industry, but AWWA is also making a concerted effort to stretch its boundaries.
We’ve all heard the adage, “Work smarter, not harder,” but are we living it in the water industry? While the status quo may have merit and is almost certainly more comfortable, these trying times of big problems and small budgets beckon a new approach — to get smarter about water. You likely know the term “smart water” as it pertains to instruments that collect and interpret data, but the focus of this edition of Water Online The Magazine is to first engage the data-collecting instrument within each of us — our brains. By Kevin Westerling, editor, Water Online
There are certain requirements incumbent upon the wastewater operator when the volume and nature of waste coming into the wastewater treatment plant changes — first and foremost of which is recognition. That’s the easy part...
Pennsylvania American Water (PAW) was receiving complaints about the unsightly color of their water, which contained manganese well above U.S. EPA guidelines. The quest began for a cost-conscious and easy-to-operate solution (appropriate to a small, stand-alone system) that would restore water quality by greatly reducing both manganese and iron.
USAID Water Strategy: Leveraging Science, Technology, And Innovation
USAID recently published its five-year Water and Development Strategy that defines its approach to water programming. Described as the government’s first comprehensive strategy aimed at integrating water into all U.S. development funding and programs and a good first step, this 32-page document provides a framework for saving lives and advancing development through innovative investments in water, sanitation and hygiene.

WERF Research Helps Cincinnati Use Innovative Biomarkers To Assess & Monitor Water Quality In National Scenic River
In 1986, ambient water quality criteria recommendations from the USEPA were developed for recreational waters using E. coli as an indicator organism. With the benefit of advances in environmental microbiology, molecular tools and quantitative microbial risk assessment (QMRA), USEPA has released the recreational water quality criteria (RWQC) recommendations that reflect the risk to human health from fecal contamination.

Seattle Public Utilities Case Study: Using A Business Case Evaluation To Identify The Most Desirable Rehabilitation Outcome
A recently published WERF report, Flood Grouting for Infiltration Reduction on Private Side Sewers (INFR5R11) provides results of a field test of the flood grouting process to seal laterals, sewer mains, and manholes. Prior to obtaining approval to proceed with this pilot project, a “business case” was prepared to compare the total life-cycle cost of the proposed option to other alternatives, which included joint grouting, pipe bursting, cast-in-place pipe (CIPP) lining, and replacement with upsized pipe. The amount of flow reduction was measured and compared that to the total project costs as tracked through Seattle Public Utilities’ cost accounting system. Researchers looked at the potential for using the technology to reduce the risk for future backups in Seattle’s Broadview neighborhood, as well as its applicability in other locations.

Advanced Pump Design Enhances Performance, Thrills Customers
With lift stations set among households and a pristine lake, failure is not an option for the Valley Rural Utility Company in Lawrenceburg, IN. The old lift stations were costing up to $30,000/year to maintain, due to poor design and persistent clogging. A new Flygt N-Pump has changed the utility’s course, however, proving with one (easy) installation the cost savings that can be gained through advanced impeller technology and remote SCADA operability.
